Fluoride release film also known as fluorine film, its main purpose is to isolate sticky items, such as silicone tape, PI tape, etc. During production, storage, or transportation, fluorine release films play a role in protecting the adhesive from contamination and deterioration. Currently, the most widely used carriers are tape or adhesive products.

nature

1. It has good UV aging resistance, chemical corrosion resistance, and solvent penetration resistance.

2. The colors are generally transparent and milky white.

3. There is no migration phenomenon, eliminating the danger of the silicone release film transferring to the material it adheres to.

4. Controllable release force, high glossiness, high cleanliness, residual adhesion of 94%, fluorine release film with good surface properties.

Technical indicators

Generally speaking, the technical indicators of fluorine release membranes are mainly divided into: room temperature peeling force, aging peeling force, and residual adhesion rate.

1. Normal temperature peeling force:

The peel force data obtained through standard tests at room temperature is in N/25mm and can be converted into several grams. A peeling force of less than 10 grams, which is 0.10N/25mm, is generally referred to as light peeling. A peeling force of less than 20 grams, which is 0.20N/25mm, is called middle peeling. The peeling force of 35-45 grams, which is 0.35-0.45N/25mm, is commonly known as re stripping. The peeling force of 60-80 grams, which is 0.60-0.80N/25mm, is commonly known as heavy peeling. There is also a stripping force of 1.00N/25mm, which is more than 100g, commonly known as overweight stripping. The peeling force of 3-4 grams, which is 0.03-0.04N/25mm, is commonly known as silent peeling.

2. Residual adhesion rate:

Refers to the force of the fluorine release film after the first peeling and the second peeling, obtained from the calculation of Teflon high-temperature tape.

3. Aging peeling force:

Aging peeling force refers to the peeling force measured after a certain amount of time or high temperature after adhering to the product or tape. Generally speaking, the peel strength data measured after aging is generally slightly higher than the peel strength at room temperature.
